ObjectiveTo study relationship of abnormal physiological curvature of cervical vertebrae and cervical spondylosis.Methods 200 patients with cervical spondylosis and 200 patients without cervical spondylosis were randomly selected from May 2013 to June 2013 in the hospital, they were allocated to the observation group and the control group. Lateral positions of cervical vertebrae of patients in two groups were detected by X-ray. Shapes of curvature of cervical vertebrae of two groups were compared and the difference of probability of abnormal physiological curvature of cervical vertebrae of two groups was observed.Results In the observation group, there were 179 patients with abnormal curvature of cervical vertebrae accounting for 89.5% and 21 patients with normal curvature of cervical vertebrae accounting for 11.5%. In the control group, there were 69 patients with abnormal curvature of cervical vertebrae accounting for 34.5% and 131 patients with normal curvature of cervical vertebrae accounting for 65.5%. Conclusion Abnormal curvature of cervical vertebra is common in patients with cervical spondylosis, which is very meaningful for clinical treatment of cervical spondylosis.%目的：研究颈椎生理曲度异常与颈椎病发病之间的关系。方法选择2013年5~6月医院颈椎病病患200例和无颈椎病患者200例，分为观察组和参照组。参照组与观察组均进行颈椎侧位的X线摄片，对比研究两组人员颈椎曲度的形态，观察颈椎生理曲度发生异常的概率的差异性。结果观察组出现颈曲异常的有179例，占总人数的89.5%，颈曲正常的有21例，占总人数的11.5%；无颈椎病人员颈曲异常的有69例，占总人数的34.5%，颈曲正常的有131例，占总人数的65.5%。结论颈椎曲度异常在颈椎病患者中是普遍存在的，这对颈椎病的临床医治是很有意义的。
